Description

A kind of rotor structure of permanent-magnet synchronous direct driving motor
Technical field
The present invention relates to a kind of rotor structure of permanent-magnet synchronous direct driving motor.
Background technology
Traditional permanent magnet machine rotor all adopts the solid shafting structure, and the drive end of motor needs shaft extension and stretches out, and on armature spindle, is with the yoke that silicon steel sheet is made, and yoke also need adopt certain mode to compress and fix.This structure can make that in the low-speed permanent magnetic direct-drive motor weight of rotor is bigger, and moment of inertia is big, and the control precision of motor is impacted.Conventional surface subsides formula permagnetic synchronous motor is to carry out the location and the installation of permanent magnet through the form that rotor yoke is processed into dovetail groove in addition.When adopting this structure, if the dovetail groove depth, the interelectrode magnetic leakage of motor can be bigger, reduced the utilance of permanent magnet; If dovetail groove is shallow, the installation of permanent magnets again can be very difficult.
Chinese patent 02136825.2 and 200420083544.0 discloses a kind of mechanical fixed structure of permanent magnet and a kind of rotor core structure of magneto respectively; Both all use guard ring and reinforcing ring to come to the permanent magnet location and reinforce at the permanent magnet two ends; But this mode will be processed a lot of screws on rotor yoke; Exist processing technology complicated, the problem that manufacturing expense is high.Chinese patent 200810027409.7 and 93208901.1 discloses a kind of p-m rotor and modified model rare earth AC servo motor respectively; Both all are employed in and drive dovetail groove on the magnet yoke blanking sheet and fix permanent magnet; Though this kind structure mounting process is simpler; But the degree of depth of dovetail groove can increase the leakage field of motor, reduces the utilance of permanent magnet, designs can have a strong impact on motor performance when unreasonable.
Therefore, how to design and be applicable to more reasonably rotor of permanent-magnet synchronous direct driving motor and structure, become those skilled in the art and want the problem that solves.
Summary of the invention
The present invention provides a kind of rotor structure of permanent-magnet synchronous direct driving motor, and this rotor has in light weight, is connected simply with load, and area of dissipation is bigger, and globality and balance are good, the installation accuracy advantages of higher of permanent magnet.
For achieving the above object, the present invention adopts following technical scheme:
Permanent magnet synchronous direct of the present invention drives motor rotor construction, comprises that the center is the axle of hollow-core construction, is evenly distributed with circular hole on the annular end face of said axle, is used for fixing the rotor flange dish.Be with rotor field spider on the described hollow-core construction axle, rotor field spider is opened some holes along circumference.Because support is thinner, simultaneously opened the hole again, make the weight of this rotor have largely and alleviate.Be with the permanent magnet installing ring on the rotor field spider, the permanent magnet installing ring is an annular, and rotor field spider, permanent magnet installing ring and hollow-core construction axle coaxial arrangement and one machine.Upper edge, the annulus of this permanent magnet installing ring surface circumference equidistance circumferential location hole of some permanent magnets of arranging, the outer at round ring magnet installing ring two ends is processed with the baffle plate on a little higher than surface, and this baffle plate is used for the axial location of permanent magnet.
Described rotor permanent magnet is installed on the described permanent magnet installing ring.Described rotor permanent magnet adopts NdFeB material.
Insert the aluminum alignment pin in the described rotor permanent magnet circumferencial direction location hole.
Described rotor flange dish upper edge circumference has evenly been opened some holes, and these holes are used for linking to each other with load.
The present invention can be widely used in can improving the heat radiation of motor in the low-speed permanent magnetic direct-drive motor, improves stable motor running property and motor properties.

Embodiment
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1-4 is depicted as the rotor structure of permanent-magnet synchronous direct driving motor of the present invention.
Fig. 1 is the drive end structural representation of permanent-magnet synchronous direct drive motor rotor.As shown in Figure 1, this rotor comprises hollow-core construction axle 1, is evenly distributed with circular hole 2, atresia on another annular end face on the annular end face of described hollow-core construction axle 1.Be with rotor field spider 3 on the described hollow-core construction axle 1, described rotor field spider 3 is uniformly distributed along the circumference porose 4.Be with permanent magnet installing ring 5 on the rotor field spider 3, permanent magnet installing ring 5 is an annular, and rotor field spider 3, permanent magnet installing ring 5 and hollow-core construction axle 1 coaxial arrangement and one machine.The annulus surface of permanent magnet installing ring 5 is placed with the circumferential location hole 6 of permanent magnet along the circumference equidistance, and the outer, annulus two ends of permanent magnet installing ring 5 is processed with the baffle plate 7 on a little higher than annulus surface.Whole rotor one machines; Make the globality and the balance of rotor better; And the structure of hollow shaft and rotor field spider has increased rotor area of dissipation and the weight that has alleviated rotor greatly; Improve the radiating condition of whole rotor, improved the running stability of rotor, more helped the low cruise of motor.
Fig. 2 is that the permanent magnet synchronous direct of having installed behind permanent magnet and the alignment pin drives the motor rotor construction sketch map.As depicted in figs. 1 and 2, tile shape permanent magnet 10 is installed on the described permanent magnet installing ring outer surface 5.When permanent magnet 10 is installed, in the location hole 6 of permanent magnet, insert alignment pin 11 earlier, and do anticreep and handle, alignment pin adopts aluminium.Alignment pin 11 is the inner surface and the permanent magnet outer surface of outstanding permanent magnet installing ring 5 not.Bonding when permanent magnet is installed, after installing, adopt epoxy glue etc. to filling in the gap, and heating cure.Adopt this mode that permanent magnet is installed, technology is simple relatively, has guaranteed precision, can make full use of the magnetic energy of permanent magnetic material again.
Fig. 3 and Fig. 4 are respectively the ring flange of permanent-magnet synchronous direct drive motor rotor and the rotor overall structure sketch map after rotor structure sketch map and both installations.Like Fig. 3 and shown in Figure 4, equally distributed circular hole 2 is to be used for fixing rotor flange dish 8 on hollow-core construction axle 1 annular end face.Rotor flange dish 8 upper edge circumference evenly have some holes 9, and described hole 9 links to each other with load.
The present invention can be widely used in can improving stable motor running property and motor properties in the low-speed permanent magnetic direct-drive motor.Processing method and assembly technology are also simpler.
